A brother-in-law of Deputy First Minister Martin McGuinness failed yesterday in a legal challenge to being stopped and searched more than 50 times.
Marvin Canning claimed the powers used by police are incompatible with his human rights.
But Mr Justice Treacy ruled that the procedures under the Justice and Security (NI) Act 2007 were lawful.
Mr Canning (54) from the Glendara area of Derry, claimed he was being victimised.
In an affidavit, he said: “The only reason I am being stopped is because of who I am, and because of the police perception of my political beliefs.”
Police accepted that, as of May last year, he had been subjected to stop and search powers around 50 times.
A chief inspector claimed this was because Mr Canning is a dissident republican. He stated in court papers: “There exists reliable and credible intelligence to support reasonable suspicion that the applicant has been involved in terrorist activity.”
Mr Canning, who has no previous convictions, categorically denies this.
